“The children seem to have scooped up clay-rich mud from the floor and smeared it on a stalagmite against the far wall, then drew curved, sinuous shapes in the wet clay with their fingers.

“On the next round of 600 mg, four percent of kids in the placebo group made it through, while 67 percent of those in the treatment group did. And 2.4 percent in the placebo group could tolerate 1,000 mg of peanut protein, compared to half the treatment group.”
